SYNCHRONIZE_RCU_BH(9)                     Driver Basics                     SYNCHRONIZE_RCU_BH(9)



NAME
       synchronize_rcu_bh - wait until an rcu_bh grace period has elapsed.

SYNOPSIS
       void synchronize_rcu_bh(void);

ARGUMENTS
       void
           no arguments

DESCRIPTION
       Control will return to the caller some time after a full rcu_bh grace period has elapsed,
       in other words after all currently executing rcu_bh read-side critical sections have
       completed. RCU read-side critical sections are delimited by rcu_read_lock_bh and
       rcu_read_unlock_bh, and may be nested.

       See the description of synchronize_sched for more detailed information on memory ordering
       guarantees.
